Abstract: The present disclosure relates to a method and a device for providing a V2X service in a next-generation radio access technology (New RAT) and provides a device and a method for controlling sidelink communication by a terminal, the method comprising the steps of: receiving sidelink control information including sidelink reservation resource information from a second terminal; determining whether to transmit coordination information; and when transmission with respect to the coordination information is determined, transmitting the coordination information including one of collision indication information, preference resource information, and non-preference resource information to the second terminal.

Abstract: The present embodiments relate to a method and a device for reducing an overhead of positioning reference signal transmission, the method comprising the steps of: receiving configuration information for a positioning reference signal from a base station; receiving, from the base station, a plurality of wide beams through which the positioning reference signal is transmitted, on the basis of the configuration information; reporting information on an optimal wide beam determined from among the plurality of wide beams to the base station; and receiving, from the base station, a plurality of narrow beams through which the positioning reference signal is transmitted, on the basis of the optimal wide beam.

Abstract: A method for beam alignment through location recognition in a wireless communication system and an apparatus therefor are provided. The method includes a first process of configuring a beam set including beams based on relative location information of a terminal, a second process of receiving reference signals (RSs) from the terminal by using the beams, and a third process of determining an optimal beam from among the beams included in the beam set, and the third process includes configuring a window including adjacent beams in the beam set, measuring beams within the window by using the RSs, determining a local optimal beam from among the measured beams, and re-configuring a window based on the local optimal beam.
